Manser Hybrid Lead Halide Perovskites for Light Energy Conversion: Excited State Properties and Photovoltaic Applications 1904 .txt text/plain 368 14 20 Advancements in thin film processing and our understanding of the underlying structural, photophysical, and electronic properties of these materials over the past several years have led to development of perovskite solar cells with power conversion efficiencies that rival much more mature first- and second-generation technologies. Time-resolved pump-probe spectroscopy serves as a principle tool in these investigations to analyze excited state decay kinetics and optical nonlinearities in perovskite thin films. cache/d504rj4556c.txt txt/d504rj4556c.txt
